Hypomagnesaemia.

In the management of electrolyte abnormalities along with hypokalaemia and hypocalcaemia, etc, presence of hypomsgenesaemia should be thought of even when serum magnesium is within normal limit as magneium is a predominantly intracellulr ion. Two cases of hypomagnesaemia as one of the factors of electrolyte distrubances are communicated in this write-up.

A rare variation of deep femoral vein.

Venous pattern particularly in the lower limbs is of great clinical importance, while ligating the veins to prevent the spread of thrombus. Normally deep femoral vein drains the area supplied by profunda femoris artery, follows the pattern of branches of this artery and ends independently into the femoral vein. However in few cases it establishes communication with popliteal vein of femoral vein at a lower level. In the present study the deep femoral vein replaced most of the popliteal vein by establishing communication with the tibial veins.

A retrospective study of 1247 cases of intracranial tuberculomata diagnosed by computerized tomography.

Tuberculomata in the brain are a common feature of intracranial tuberculosis, especially in the sub-continent. With the advent of computerized tomography, a diagnosis can be made, in many instances. In this study, 1247 cases of CT diagnosed intracranial tuberculomata were analysed retrospectively with regard to the age, sex and symptoms of the patient as well as the number, site and distribution of the lesion within the brain. Tabulation with respect to age revealed that patients with ages ranging from 1-30 years accounted for 60% of the cases. The male to female ratio was approximately 60:40. The parietal hemisphere accounted for 46.75% of the cases. Left sided lesion were more common when compared with the right (statistically significant). We postulate that this increased occurrence of left sided lesions is due to the hematogenous mode of infection and increased blood flow to the dominant hemisphere.
